KEB dV/dT filters reduce the peak voltage levels seen by the motor in VFD applications.

 

dV/dT chokes help protect the motor insulation and increase operating lifetime by reducing motor heating.

FEATURES

LOW INDUCTANCE DESIGN

KEB’s dV/dT chokes do not skew the VFD’s motor model and negatively affect motor performance.  They can be used with either PM or Induction Motors.

OPERABLE UP TO 16kHz

KEB dV/dt filters can be operated safely and effectively with high output frequencies from the drive – up to 16kHz carrier frequency.

REDUCED EMI

Our dV/dt motor chokes have the secondary benefit of reducing EMI emissions (>250kHz range) from the VFD output.
